1 This invention relates to windows and particularly to a compositewindow structure in which various window parts and accessories areuniquely combined .to effect improved results, as well as new anddesirable features.

One of the objects of my invention is to provide a window composed ofopenable sections, and wherein the sections have double paneconstruction and weather-tight joints to avoid the need for separatestorm windows and to reduce heat losses in air-conditioned roomsgan'dthe like.

As another object my invention comprehends the provision of asectionalized window wherein a window shade is confined in asubstantially dust and dirt-proof space between two glass panes whichcomprise the section and maybe retracted or extended between the paneseffectively to cover a desired portion of the section. 6

My invention has for another object the provision of a window composedof a pluralityof sections separately opnable by rotational movement andthus swingable to various positions for providing ventilation or makingthe outer sur faces accessible for washing. I v

Another object, of the invention is to provide a window structure of theclass referred to which is adapted to the use of metal frame parts.

It is a further object of this invention to provide awindow structureinwhich a plurality of sections are each supported for rotational movementbetween closed .and adjusted open positions, and each such section isseparately removable for repairs.

An additional object of my invention is to provide a window structure inwhich the frames of separately movable sections may be fabricated ofrelatively thin metal and so constructed that adjacent parts interlockwhen closed.

Other objects and advantages of theinvention will be apparent from thefollowing description and the accompanying drawings in which similarcharacters of reference indicate similar parts throughout the severalviews.

In the four sheets of drawings:

Fig. 1 is a front elevational view of an assembled sectional windowembodying my invention in a preferred form;

Fig. 2 is a side sectional view of the window assembly shown in Fig. 1wherein the'section is taken substantially on a line2-2 of Fig. 1 andthe mounting of the window in a structure is fragmentarily illustrated;

Fig. 3 is a fragmentary side sectional view drawn to an enlarged scaleand wherein thesection is substantially-as depicted by a .line 3-3 inFig. 1;

4 Claims. (01. -53) Fig. 4. is a broken fragmentary view i1lustrat-' ingparts of the structure as depicted in Fig. 2 but drawn toa considerablylarger scale;

Fig. 5 is a fragmentary side sectional view taken on line '5-5 of Fig.'1, and drawn to a large scale to illustrate certain structural detailsof a portion of the window structure depicted in Figs. 1, 2 and 3 Fig. 6is a fragmentary sectional view taken substantially on 'a line 66 ofFig. 1 and drawn to an enlarged scale; and

Fig. 7 is a fragmentary front elevational view of a corner portion of apart of the window shown in Fig. l.

Considered generally and with reference to the drawings, my preferredwindow, the exemplary embodiment of which is depicted in Figs. 1 and 2for illustrative purposesincludes, an outer frame it within which sashesor sections [2, l3, l4 and I5 are mounted for separate rotationalmovement between closed and adjusted positions. When closed, as depictedin Figs. land 2, the section sashes fit into and substantially fillitheinterior of the frame I 0 and are disposed in substantially coplanarrelationship with the general plane of the frame. In such closedposiiton, weatherproof joints are provided between the section sashesand the frame, as well as between adjacent sashes. As depicted in dotand dash lines at He in Fig. 2, each section maybe individually openedby rotational movement about a fixed. axis.

It is to be understood that while the illustrated window embodies fourmovable sections, that number of sections may be varied from one to alarger number without departing from the' ends to form a rectangle andhaving the open,

faces of the channels disposed inwardly of the frame. The channelmembers which comprise the frame are desirably made-of metal and may,for example, be secured together by'welded'j oints. When installed in awindow opening, such as 20; in awall -22 andasrillustratedin Figs. Zanda, the jointsat the outer corners of the frame are desirably sealed witha, calking compoundas indicated at .23.

The side channel members it and of the frame comprise the window jambs.

By preference and as depicted in Fig. 6, weather stripping for the sidesurfaces of the window sections is provided by strips '24 of materialseated in the open channel face of the side channel members andextending longitudinally therealong. Desirably, the material hasresilience as well as wear-resisting qualities, such as are possessed byartificial or natural rubber. In the disclosed window, the strips 24normally extend inwardly of the inner channel surfaces for closeengagement with the section sash surfaces and to take wear resultingfrom movement of the sections; said strips being replaceable if undulyWorn.

Within the side channels, and at spaced positions longitudinally of thechannels, pivot stud support plates 25 are mounted for movement relativeto the channel side walls and are each outwardly of the channel by acompression spring 25. By preference, the pivot stud support plates foreach. section of the window are separate, rather than being connected ina continuous strip extending'along the channel so that each suchsupport'plate 'may beretracted separately for effecting removal of onewindow section by inserting atool, such as a screwdriver, through a slot2| in the channel side wall. Eachsuch support plate-carries a pivot:stud21 which projects inwardly of the frame and outwardly of thechannel from the face of the plate and through a suitable opening 28 inthe strip 24.

Thepivot studs 2 on opposite sides of the window frame are disposed inopposed and axially aligned pairs; each such pair defining therotational axis of a sash or window section. By preference, and asdepicted in the drawings of my preferred window structure, each sash issupported for rotational movement about pivot studs aligned-laterally ofthe-window frame anddis posed substantially at "the center line Qfthefsash. v

At thetop and bottom inner surfaces'of the frame I0, and as depictedinFig. (1, sealing strips 29 and 38 are mounted against the open faces ofthe channels it and. II, respectively, andextend longitudinally alongthose faces and laterally, thereacross. In the disclosed structure, thesealing strips 29 and 3!] are fabricated of metaland are secured tothechannels by brazing or welding, as indicated at32. p

In my preferredstructure, the sealing strips 23 and 30 are of irregularsectional shape, with their sectional shapes chosen and disposed to 30are preferably mounted in oppositely disposed relationship, so that eachof a plurality of sections may be opened by rotational movement of eachof those sections in the same direction.

In order to reduce weight and cost and yet provide a strong and durablestructure, the sealing strips 29 and 30 of my preferred window may bemade of relatively thin metal and with a hol- At the top and bottom ofthe frame and regardless of the number of window sections, the sealingstrips 29 and:

low'section, as depicted in Fig. 4. Parts of this type may, for example,be produced by forming Each of the sashes l2, 13, I4- and I5 is composed of upper and. lower frame strips and 36, respectively, and sideframe strips 31 and 38 secured together at their adjacent ends to form arectangular frame having an outside width to fit snugly between thestrips 24 and in closely spaced relationship to the jambs l8 and I9.Unless some particular design or spacing characteristics are desirable,the sash frames are usually selected to effect uniformity of the sashframe sizes in a particular window and to give a desired number ofsections, or sashes of a height which looks well with the general sizeof the Window.

As in the instance of the sealing strips 29 and :39. and for cooperativeaction with and relative to those sealing strips, the upper and lowerframe 7 strips 35 and '36,respectively, of the sashes are provided withirregularly shaped sealing surfaces 39 having characteristics like anddesirably generally similar to the sealing surfaces 33 and 34 of thesealing strips 29 an d 311. As in -th e ;in. stance ofthe sealingstripsgalsgthe sealingsurfaces 39 of the upper and lower fr ame strips31 and 38 are of substantiallygshapeand those surfaces on the edges ofsections which are adapted to engage whenthesections areclosed areoppositely disposed. Al5q, since thesections are supported forrotational movement about a central axis, thesealing surfaces of eachsection are oppositely disposed.

In my preferred sash construction; th l lqper and lower frame strips 35and 36," as well as the longitudinally of the frame strips. j Inf likeman ner, the side strips 31 and 38 ,not ;o nly present substantiallyflat outer surfaces. forengage:- ment with the sealing strips ;2 4butjals have formed therein substantially parallel- -groo.ves 44 and 45extending longitudinally of t e lug strips and aligned to adjoin thegrooves 40;andf.42-, re spectively. In each,instance, the grooves 40,42, 44 a 45 re d .,reQeirema s naL d P r n of panes ofassfiflppdfllandar o a size. and shape to receive 's ea ling compoundedto s eal the glass panes into the sash frame. When thus disposed in thegrooves, the glass'panes are preferably carried in the frame in spacedand substantially parallel relationship toprovide a dead air space 41between the panes. Such dead air space'not only has heat-insulating-properties but also furnishes a clean spacefor. the mounting of anextensible shade 48; as depicted Fig. 3.

While three of the sash framestrips; such as I theglower and sideframestrips 33, 31 and; 38,

may be permanently .secured gtogether as by Welding, it is preferable,thatpnc of. the frame strips, such as the upper 'frarnefstrip 3, ,shallbe removable for servicinggrepla cement.of glass panes orthe like..Thus,'in my preferredjsash structure, the upper frame strip35.' i's.reniovably secured in place relative .toithe sideistrips'3l-and 38 byangle-type inserts, such-as 52, shown in r Fig. 7." lhese inserts fitinto opposite-ends ofthe upper frame strip 35 and-areisecured therein byremovable fastening :me'an's; 1 sucn" asscrews 53,. exposed on theinterior surfaceiof' the window.

At it's upper edgerthe shade is secured toannexible element 51,- such as a-ehain,;wire or thread which 'extendstothe outside of the window section through openings 58 and 59 in thewalls of the hollow frame strip 35. Preferably, the flexible element 5'!carries enlarged beads 60 or the like at spaced intervals which providecatches for holding the shade in an adjusted position.

In order effectively to screen a window of the disclosed construction soas to avoid interference of the screen with the opening of the windowsections, a screen 52 (Figs. 2 and 4) is constructed to extend outwardlyadjacent the window frame parts to which it is secured by fasteningmeans, such as screws 63; the outward extent of the screen beingproportioned to the height of the sections so that those sections do nothit the screen when they are opened. Such a screen may be attached tothe window frame in the manner described, so as to avoid the use of aseparately framed and removable screen unit.

From the foregoing description and reference to the accompanyingdrawings, it may be readily appreciated that my preferred windowstructure is well adapted to and advantageous under widely varyingweather conditions. That is, the double pane construction affords apermanent storm window effect without seasonal removal and insertion ofa separate storm window, and without interfering with desiredventilation at any time. Rotational movement of the window sectionsexposes both the inner and outer window pane surfaces for washing fromthe inside without difficulty. The separate adjustability of thesections and their shades provides for adjustment to suit a Variety oflight conditions, as well as for ventilation. The louver eifect of therotatable window sections also permits adjustment for ventilationwithout leakage during rain. With the window structure disclosed, theentire window may be assembled as a prefabricated unit and installed, assuch, in a wall opening of the required size. With the sealing surfacesprovided, the various joints between the window parts are weather-tightand those window parts will not rattle. When constructed of metal, itaffords a fireproof window structure and when that metal isnon-corrosive, the parts remain clean and do not require painting.Furthermore, when the disclosed hollow metal sections are utilized, thewindow is relatively light in weight and not unduly expensive tomanufacture.

While I have illustrated a preferred embodiment of my invention, manymodifications may be made without departing from the spirit of theinvention, and I do not wish to be limited. to the precise details ofconstruction set forth, but desire to avail myself of all changes withinthe scope of the appended claims.
